IMPROVEMENT IN TRACE-BUCKLES.

Specification forming part of Letters Patent No. 140,463, dated July 1, 1873; application filed May 2l, 1873.

.each other, one of which is provided with a hinged end, carrying a pin for fastening the trace, the parts being so constructed as to form a closed case for protecting the trace and adding to its strength and security.

In the drawings, Figure 1 represents a top or plan view of the improved buckle 5 Fig. 2, a side view of the same, showing the hinged section raised for fastening the trace 5 and Fig. 3, an end view of the same.

- The letter A represents the stationary part of the buckle, and is provided with vertical llangesa a, and horizontal ribs or guides b b, and with a depressed projecting end, d, provided with a slot vfor connecting the saine to the hame-strap. Upon this stationary section A is arranged a sliding section, B, having a hinged front portion, C, near the front part of which is secured a pin, e, for fastening the trace in position. This section B is provided with grooves f on its sides, which are adapted to the ribs b on the section A, and is capable of sliding thereon.

The trace is placed in the case, and the sliding section B is brought to the position shown in Fig. 2-that is, the hinged section C is elevated-and when the trace is adjusted to the proper length the hinged section is lowered, and the pin c caused to enter one of the holes punched in the trace, and the sliding section is then pushed back until the pin e strikes the shoulder g, formed by depressing the front end of the section A.

By this means the strain on the pin eis supported by the said shoulder, and the liability of breakage is prevented. In order to further prevent the backward movement of the sliding section, its rear end bea-rs against flanges c c on the end of the section A, which prevent it from being drawn back oft' of the sec tion A, when there is an unusual strain on the pin e. l

The section A is provided at each side with lateral projections D D, having `slots for the purpose of attaching the back and belly bands to; but to this feature I lay no claim, as it is not essential.

I claim as my invention- `The sliding' section B having a hinged front end, O, carrying a pin, e, and provided with' grooves ff, in combination with the section A, its guides b I), and with or without the flanges c c and shoulder g, substantially as described, for the purpose set forth.

In testimony that I claim the foregoing I have hereunto set my hand this 12th day of May, 1873.

THOMAS BROWNLEE.
